Application filed May 29, 1893- Serial No. 475,897. (No model.)

To all whom it may concern.-

Be it known that I, ORIN PIPER, of Manohester, county of Hillsborough,State of New Hampshire, have invented an Improvement in Loom-Shuttles,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention has for its object to provide a shuttle with novel meansfor holding the spindle in position in the shuttle; also to improvementsin the shuttle spindle whereby it is better adapted to maintain upon itthe shell, a bobbin, or cop, on which the thread is wound.

In accordance with my invention I have provided the spindle-head with atail-piece that co-operates with a holder which engages the tail-piece,the said tail-piece and holder being so constructed as to yield one partwith relation to the other when their contact is being made or broken.The shuttle spindle as improved by me is split for part of its lengthand provided with a wire-like spring loop, the ends of the loop beingattached to the spindle preferably near its point, the sides of thespring loop contacting with the interior of the shell of whatever formof material on which the thread is wound.

Figure l is an under side view of a loom shuttle embodying my invention;Fig. 2, a section in the line as, the dotted lines showing the spindleturned out for the removal of the shell, bobbin or cop the near side ofthe spindle being broken out to show the spring loop in elevation; Fig.3, a section in the dotted line a Fig. 4 shows the forward part of thespindle in elevation at right angles to Fig. 1, with the spring loop inposition. Fig. 5 shows the spindle as engaging a shell of the kinddesignated as a cop.

The shuttle bodyA of wood or other material, has a pin A for the head aof the spindle b. The shuttle bodyis also provided with a holder 0,shown in Figs. 1 to 3, as a metal block having a concavity, the mouth ofwhich is constructed to receive the split or yielding tail-piece 01,said tail-piece extended from the spindle head springing into the monthof said holder, as shown in Figs. 1 and 2 by full lines when the spindleis in working position. The pin 20 in Fig. 5 confines the holder in theimproved spring 6 is made as shuttle. The blade of the spindle is splitor slotted for part of its length, and in this slot I have secured ashell holder e, composed, as shown, of a wire bent upon itself andexpanded to present a loop with yielding sides, the said sides beingpreferably corrugated. This shell holder, as represented in Fig. 2,engages the interior of a bobbin and aids in keeping it in place, but itmay engage and hold a cop 22 as in Fig. 5. To further aid in keeping theshell in place, especially when in the form of a bobbin, I have added tothe shuttle a bobbin engaging barf, which is embraced by the groove f ofthe bobbin when the latter is turned into the shuttle body, as in Fig.2, full lines.

Prior to my invention I am aware that loom shuttle spindles have haddevices to engage a shell carrying the thread, but such devices have notbeen made in the form of a spring-acting loop.

I do not claim a spindle blade which is split and has its split endextended behind the pivotal point of the blade in the shuttle; nor do Iclaim a corrugated spring placed in a groove in one side of the spindleblade. My a loop, and the end of the loop where the wire forming theloop is brought together, is connected to the spindle, exposed outsidethe spindle blade to be acted upon by the bobbin or cop to which it isto be held. I do not claim a loop which is expanded and contractedautomatically.

Having described my invention, what I claim as new, and desire to secureby Letters Patent. is-

1. The shuttle body, the tail-piece holder therein, and the spindlehaving a blade, a head, and a tail-piece extending from said head in adifferent plane from that occupied by the blade, the tail-piece beingheld in the holder elastically, substantially as described.

2. The shuttle body, the tail-piece holder having a recess in its lowerportion, and the spindle having a blade, a head, and a tailpieceextending from said head in a different plane from that occupied by theblade, the tail-piece being split longitudinally to form elastic limbsto be sprung into the recessed holder, substantially as described.
